Between the previous post and this one,
the death of Little Richard has taken place,
see obituary thread.

a wop bop a loo bop a lop bam boom
or something rather like that ...

would that be called scat singing? or something else?
'rock and roll,' to be sure, but I mean
the singing that is sounds that aren't words.

The obit thread references a far lesser-known performer
who took it even further than Richard Penniman did.
I haven't listened to those links yet.
It might be instructive to compare that singer
with Leo Watson, who died before 'rock and roll' even happened.

The exuberant non-intellectual noisemaking with the voice
seems to recall minstrelsy, I'm not certain how.
I can't say that 'minstrels' did scat singing.
The attitude, the attention-getting provocative commotion,
and the emphasis on rhythm and comedy,
is what I am looking at here.
